These new battery "gigafactories" are really bringing the price of batteries down.

One article said $190 per kilowatthour for Tesla batteries. That makes the 130 kilowatthour battery of the Sun Flyer 4 a theoretical $25,000 or so. Not too bad compared to the price of gas. Sun Flyer claims a price of about $16 per hour to fly which I could believe.

Maybe sometime, but not yet !
Best estimate would be the latest known price for Teslas Powerbank 2 modules, which was $350,000 per MWh..(for bulk orders)
...which would make that 130 kWh pack more like $45,000. ,!
